Pressing the center button activates the glass. Touching the corresponding label of the desired function will activate it. The glass will be deactivated after 30 seconds of inactivity.

Chronograph Function - Chrono Function with split time capability.

Barometer Function - The hands on the watch will superimpose to indicate the variance in the atmospheric pressure. The T-Touch measures these variations to indicate the meteorological trend. When the atmospheric pressure rises, the skies clear. The hands will move toward the right. When the atmospheric pressure decreases, it becomes cloudy. The hands will move toward the left. The digital display will give the absolute pressure in hectoPascal.

Altimeter Function - When the altimeter function is activated, the watch is turned into a barometric altimeter and displays the altitude in relation to average sea level. The T-Touch Multi-function can be set to display the altitude in meters or feet.

Thermometer Function - The T-Touch is able to display the temperature in Celsius or Fahrenheit while in the thermometer mode. For the most accurate temperature measurements, the watch should be removed from the wrist for at least 15 minutes so that body temperature does not effect the reading.

Compass Function - While in the compass mode, the T-Touch with the minute hand indicates the geographical North Pole taking into consideration the magnetic deviation. The T-Touch Multi-function will indicate the degree of magnetic deviation between the geographic and magnetic North Pole on the digital display.
